' This invention relates to; typewritingmachines, and more particularlyto acardguiding device arranged atth'e frontloff the platen and closetothetype-har guide.

One featurebrthe invention is the provision of means for preventing theleading edges'of forms-or Work-sheets fromruhbing against the ribbonvibrat'or or typebar guide Whilelbeing'introduced into the ma chine andbrought up. to typingfpos tion. ,7 Another featureis the provisionotxmeans for guiding the side edges of :cards or stlfi Work-sheets fromf the typebar guide and ribbon- Vibrator When the carriage 1s movedlaterally, thus. preventing the edges of the sheets from fouling thetypefloar 'guide or coming in'to'contact 'vvith" ,theinkribbon. c vAIfurtherfeatureincludesmeans for holding the ork-sheets.- toward theplaten, so as m prevent the upper-casetype fromfshadowing orrprintingupon the worksheets when the ribbon has been shiftedto ilo r ng thelower vportion 'thereof to: the, printing line.

.115 haying bear'ings in-the right and leftends user the mechanism"described isthat retains said shanks within the sockets 27, so

as to secure the wireguide in position upon the segment 10. In Figure 2a plurality of interleaved work-sheets S have been inserted beneath theplaten, and it will be noted that as the sheets emerge from the underside of the platen, the leading edges of the sheets engage the inclinedportions 32 of the wire-guide 29, and are thereby defiected upwardlytoward the side members 35, which then direct the sheets upwardly andrearwardly toward the platen.

Figure 3 illustrates the position of worksheets which have been insertedunder the platen and brought up to position beneath the wing-scale l9,and properly adjusted in a collating chute 37, and the feed-rolls l3 and14 returned to eifective position to enable the sheets to be run to theprinting line. Now, when the carriage is moved laterally duringoperation of the machine, the side edges of the work-sheets will bedeflected away from the type-bar guide and ribbon, due to the fact thatas the edges or the sheet move from under the wing-scal'esin eitherdirection of travel of the carriage, said edges immediately come underthe influence of the tongues 33 of the wire-guide which deflect thesheet-edges toward the platen sufiiciently to clear the type-bar guideand ribbon-vibrator. Thus, it will be seen that the wireguide forms, ineffect, a continuation of the wing-scales, so that any tendency of thework-sheets to spring away from the platen, and become caught againstthe type-bar guide, or rub against the ribbon, is entirely overcome. Thetongue 34 is also effective to hold the work-sheets toward the platen,as indicated by dot-anddash lines in Figure 2, and thus prevents theupper-case type from shadowing or printing upon the worksheets when theribbon is shifted to upper position.

. Variations may be resorted to within the scope of the invention, andportions ofthe improvements may be used without others.

Having thus described my invention, I claim.

1. In a typewriting machine, in combination, a platen, a segment havingsockets therein, a type-bar guide, and a wire-guide having shanksreceived in said sockets, the upper portion of said wire-guide beingbent of the plane of said wingscales, and having portions thereofinclined toward the platen, so that the side edges of work-sheets, movedlaterally with the carriage, ride over said inclined portions, causingthe sheets to be guided toward the platen sufficiently to clear saidtype-bar guide and ribbon-vibrator.

3. In a typewriting machine, in combination, a carriage, a platen, atype-bar seg ment, a type-bar guide, a ribbon-vibrator, wing-scalesdisposed on opposite sides of said type-bar guide and having their innerside edges opposite said ribbon-vibrator, and a wire-guide disposedabout said type-bar guide and including a pair of oppositelydirectedtongues terminating closely adjacent the inner side edges of saidwing-scales and slightly to the front of the plane of said wing-scales,said wire-guide having portions thereof bent and inclined toward theplaten, so that the side edges of work-sheets, moved laterally with thecarriage in either direction, ride over said inclined portions,deflecting the sheets toward the platen sufficiently toclear saidtype-bar guide and ribhon-vibrator.

4. In atypewriting machine, in combination, a carriage, a platen, atype-bar segment having a pair of sockets therein, a type-bar guide, aribbon-vibrator, wing-scales disposed on opposite sides of said type-barguide and having their inner side edges opposite said ribbon-vibrator,and a wire-guide forming a frame about said type-bar guide andribbon-vibrator, said wire-guide including shanks received in saidsockets, and having its upper portion bent to form a pair ofoppositely-disposed tongues terminating at points closely adjacent theinner side edges of said wing-scales and slightly to the front of theplane thereof, said tongues having portions thereof bent so as to beinclined toward the platen, said wire-guide also including a verticallyand rearwardly disposed tongue extending above the printing line of theplaten, so that the side edges of work-sheets, moved laterally with thecarriage in either vdirection, ride over said inclined portions andunder said second-named tongue, so as to direct the work-sheetsrearwardly toward the platen, and thereby prevent said sheets fromengaging the type-bar guide or rubbing against the ribbonvibrator.

5. In a typewriting machine, in combination, a carriage, a type-barsegment, a typebar guide, wing-scales disposed on opposite sides of saidtype-bar guide, and a wireguide about said type-bar guide, and formingin effect a continuation of said wingscales, whereby to direct the sideedges of work-sheets toward the platen, when the carriage is shiftedlaterally in either direction.

6. In a typewriting machine, in co1nbination, a platen, a segment, aribbon-vibrator,

ii type-bars including upper and lower case type, wing-scales disposedon opposite sides of said ribbon-vibrator, and a wire-guide carried bythe segment and including a pair of oppositely-directed tongues disposed1 adjacent the front of the platen and forming in effect a continuationof said wing-scales, whereby to guide the side edges of worksheets awayfrom said ribbon-vibrator, when the carriage is shifted laterally, andalso to hold said work-sheets toward the platen to prevent theupper-case type from printing upon said sheets, when the ribbon-vibratoris shifted to upper position.

7 In a typewritingmachine, in combina tion, a platen, a type-bar guide,wing scales on opposite sides of said type-bar guide, and meansco-operating with said wing-scales, whereby to engage the side edge of aworksheet as it is moved laterally with the platen from under saidwing-scales, and guide said edge toward the platen and away from saidtype-bar guideso as to clear the latter.

8. In a typewriting machine, in combination, a platen, a segment havingsockets therein, a type-bar guide, a ribbon-vibrator, wing-scales onopposite sides of said typebar guide and ribbon-vibrator, and awireguide, including shanks received in the sockets, the upper portionof said wire-guide being bent to form a pair of oppositely-directedtongues and so positioned with, relation to the wing-scales that theside edges of work-sheets, moved laterally with the platen, engage saidtongues and are. thereby deflected toward the platen so as to clear thetype-bar guide and ribbon-vibrator.
